EMBO Rep:铂激活Toll样受体4且有助于顺铂诱导的耳毒性

2021-04-09 AlexYang MedSci原创

Toll样受体4(TLR4)能够识别细菌脂多糖(LPS),也可被一些9/10族过渡金属激活,被认为能够介导免疫超敏反应。

Toll样受体4(TLR4)能够识别细菌脂多糖(LPS),也可被一些9/10族过渡金属激活,被认为能够介导免疫超敏反应。

最近,研究人员调查了TLR4是否可以被第10组金属铂和基于铂的化疗药物顺铂激活

顺铂在儿童癌症治疗中是非常有价值的,但由于会引起永久性听力损失(顺铂诱导的耳毒性,CIO),其使用受到限制。研究人员在研究中阐述了铂和顺铂能够激活TLR4的下游通路,且与已知的TLR4激动剂LPS和镍具有相似的程度。研究人员进一步证明,TLR4是体外毛细胞中顺铂诱导的炎症、氧化和细胞死亡反应所必需的,也是体内毛细胞损伤所必需的。最后,研究人员鉴定了一种TLR4小分子抑制剂,其能够在体外抑制顺铂的毒性。

Tlr4缺失减弱了顺铂诱导的耳毒性反应

最后,他们的研究结果表明,TLR4是减轻CIO的一个很有应用前景的治疗靶点
